1991– other 1991 plates
Antique (Vintage) plates, 1991 pattern
Some confusion exists in the Motor Vehicle Regulations, which refers to registering both "antique" and "vintage" vehicles. However, these are apparently the same thing.
To be an antique, the vehicle must be at least 25 years old and be operated as a collector's item to/from exhibitions, repair/fuel facilites, and club activities but not for general transportation. Plate inscription is one to six characters in a sequence that is acceptable to Motor Vehicles. According to the Regulations, the plate should bear the inscription Antique Auto but as the example here shows, the makers of the plates don't read the Regulations.
These plates are very rare.
